POWER COAL SHOVEL.

Application led February 28, 1925. Serial' No'. 12,308.

.To all whom t may concern.'

Be it known that l', OswALn LUsoHNIG, a citizen of the 'United States,residing at Nokomis, in the county of Montgomery and State of Illinois,have invented certain new and useful Improvements in Power CoalShovelsyofr-whieh the following is a specification.

This invention relates to new and useful improvements in power coalshovels.

The primary object of my invention is to provide a shovel for loadingcoal excavated in mines int-o the cars, instead of employing manuallabor for this purpose. lith the use of my device it will not benecessary to load the coal into the cars by manual labor in the ordinaryway but merely to loosenthe coal, when the shovel 'will be the workordinarily performed b'y ten men.

W ith the 'foregoing and other objects in 'View that will appear as thenature of my invention is better understood, the same consists in thenovel ieaturesoi construction, combination and arrangement of partsillustrated in the drawings and' more articularly pointed out in theappended claims.

In the accompanying drawings, which are for illustrative purposes onlyand are therefore not drawn to scale i Figure 1 'is a top plan view of a,power coal shovel' embodying my improvements.

Figure 2 is an end view.

Figure 3 isa. side view.

Figure 4 is a vertical transverse section, taken tl'irough the 'lowerend ot the chute and its supporting means, with the parts represented onan enlarged scale.

Figure 5 is a central longitudinal enlarged sectional view ot 'the lowerend of the chute.

Figure 6 is a detail plan view of the cam roller and associated parts,and

Figure is a detail fragmentary trans verse sectional view ot the camroller and associated parts.

Referring to the drawings for a more particular description of myinvention and in which drawings like parts are designated by Ilikereference characters throughout theV several views, A. represents thebase rovided at one end with a supporting rame 1` comprising the spacedstandards 2. The base 'A is revolubly mounted by means of the turn tableB on a low truck C in order that the base may be'turned to reach coalfrom all sides., A U-shaped hinge member 3 is hingedly connected at itsends l in the eyes 5 of: suitable bearings 6 mounted on the upper endsof the standards 2. The horizontal central or intermediate portion 7`0the hinge member 8 extends under and supports the upper end of the chute8. The chute 8, which is preferably of U-shape form in cross section,lextends at right an- O'les to the plane of the base A and extendsdownwardly from the base at a suitable in; clination. The lower end ofthe chute is mounted on and operatively supported by the lower ends ofangle bars 10 fastened at their upper ends to the top of the base A, andin provided with a suitable shovel 1]., which is pivotally connected atits inner ends by the transverse bolts 11', to the lower end of thechute and may be adjusted at the desired angle by tightening up the wingnuts 12. is fulcrumed intermediate its ends on the bearing'post 13rigidly mounted on the base .and is connected at one end by means of theconnecting rod 14, cross rod iland ears 16 to the lower end of thechute., `The opposite end of lever 12 is providedwith a down wardlyprojecting pin 17 which works in a cam groove 18 having a substantially4V shape portion 19 formed in. theJ `jaeriphery of the roller 20,journaled in suitable bearings 21. mounted on the adjacent end of thelbase A. One end ofthe shaft 2110i the roller 20 is provided with apulley 22 over which a belt (not shown) is adapted to pass in drivingthe roller by power.

In practice, power is applied to drive the roller 20 which by virtue, ofits V-shaped cam groove causes the chute and shovel to reciprocate backand forth with a quick jerky movement, which constantly forces the coalup until it reaches the upper end of the chute and falls into thewaiting coal car. Attention is invited to the, ,fact that the' shovel ismade from a single piece of metal bent or folded back upon itselfintermediate its ends to form a transverse shoulder or ridge 23 whichnot only aids in forcing the coal up the chute but acts as a catch inpreventing any ofthe coal from slipping back.

.The several parts of my device may be of any desired size or dimensionsand of any suitable material.

From the foregoing description, taken in connection with the drawings,it is thought that the construction, operationandadvan-I A horizontallydisposed lever 12 llO tages of my invention will be readilyunderstoodwithout requiring a more extended explanation.

Having described my invention, what I claim es new and desire to secureby Letters Patent, is

1. A powei` coal shovel comprising a base, an upwardly inclined chuteextending at right angles to the plane of the base and hingedlysupported at its upper end upon the latter, means for operativelysupporting the lower end of the chute, means for reciprocating the chuteback and forth and a shovel hingedly connected to the lower end of thechute, said shovel formed from a single piece of metal bent or foldedvbeck upon itself at a point intermediate its ends to form atransverseshoulder or ridge, substantially as and for 'the purpose specified.

2. A power coal -shovel comprising e base, an upwardly inclined chuteextending at 4right angles to the bese and hingedly supported at itsupper end upon the latter,

means for operatively supporting the lower.

end of the chute, a shovel hingedly connected to the lower end of thechute and ,means for reciprocating' the chute and shovel 4back andforth, said means comprising a. lever fulcrum'ed to the base andconnected at one end Witlrthe chute, a roller journaled on the base andformed in its OSWALD LUsoHNIG.
